DSG-PEG 2000 is widely used in bioconjugation and drug delivery systems. It serves as a crosslinker to attach molecules like proteins, peptides, or drugs to nanoparticles or other carriers, enhancing their stability and targeting efficiency. In pharmaceuticals, it is employed to modify therapeutic agents, improving their solubility, circulation time, and reducing immunogenicity. It is also utilized in the development of antibody-drug conjugates (ADCs) for targeted cancer therapy. Additionally, DSG-PEG 2000 plays a role in surface modification of biomaterials, making them more biocompatible for medical implants or tissue engineering applications. Its versatility makes it a valuable tool in advancing biomedical research and therapeutic innovations.
